A very important distinction being made about Backlinks versus Social Buzz, in the following update from SocialMediaScience.com.
QUESTION: “We understand the exposure/awareness benefits that social networks would provide us, but the primary goal for us right now is to leverage these social networks as a means to build back links directed to our websites. We would like the ability to specify the anchor text of links to web pages that we specify, from do-follow social network pages. We would prefer these links to be embedded in the content of the articles that we create. It would be even better if we could provide a few possibilities of anchor text that would be used in the links.
